Chemical, Mechanical and Biological Recycling: A Comprehensive Study for Sustainable Waste Management
The rapid increase in solid waste, particularly plastic waste, has created significant environmental challenges worldwide. Recycling technologies play a vital role in reducing waste, conserving natural resources, and promoting sustainability. This paper presents a comprehensive study of three major recycling approaches: mechanical, chemical, and biological recycling. Mechanical recycling involves physical processing of waste materials, while chemical recycling converts waste into valuable chemical feedstocks. Biological recycling uses microorganisms and enzymes to degrade waste materials into reusable components. The study highlights recent advancements, advantages, limitations, and future prospects of these recycling techniques. The integration of these methods is essential for achieving a circular economy and sustainable waste management. Cite as: Kondekal Manjunatha. (2026).

Implementation of Six Sigma Methodology in Product Design and Development using Particle Swarm Optimization Technique
This research explores the application of Six Sigma methodology and Particle Swarm Optimization (PSO) technique in controlling defects during the product design and development phase, focusing on Polyethylene and Polypropylene production at Indorama Eleme Petrochemicals Plant. The study aims to enhance product quality, reduce production costs, and improve process efficiency by integrating Six Sigma’s DMAIC (Define, Measure, Analyze, Improve, Control) framework with PSO-based optimization strategies. Using data collected from manufacturing units, process parameters, and quality control records, the research evaluates defect trends, sigma levels, process capability indices, and cost of quality indicators before and after optimization. Results indicate significant improvements in defect reduction, yield enhancement, and process stability, demonstrating the effectiveness of combining Six Sigma and PSO in managing quality and minimizing variability. The findings contribute valuable insights for academic researchers and industry practitioners seeking innovative approaches to achieving superior sustainability performance through improved quality management and optimization techniques.

Design and Construction of a Dust Extractor for Workshop Environment
Dust is a common by-product of industrial and workshop operations such as woodworking shops, metalworking areas and construction sites. Prolonged exposure to airborne dust poses serious health risks including respiratory problems, allergic reactions and long-term lung conditions. The aim of this study is the design and construction of a dust extractor for workshop environments. This work involved design calculations, technical drawings, selection of materials and equipment. Performance tests and evaluation were carried out to ascertain the effectiveness of the prototype and efficiency of the blower according to manufacturer’s specification. The blower was coupled to the 200W motor via its shaft and fastened on the tank cover. Performance tests were carried out on the suitability of the dust extractor for removal of particles at source in various workshops and factories. The performance evaluation involves measurement of flow rate against static pressure, motor power and blower efficiency at different flow rates. Total machine efficiency in terms of quantity of dust removed showed that for 60 s, iron filings, saw-dust, cement dust, plastic dust, rice chaff, rock dust and clayey- loamy dust particles, 45g, 70g, 85g, 53g, 72g, 47g and 65g respectively were removed by the dust extractor.
